510(k) Predicate Finder
Find potential predicate devices for your 510(k) submission. Enter a K-number to find all clearances with the same product code, a three-letter product code to browse clearances directly, or search by device name.
Gram Positive Identification Panel
Microbiology
The Gram Positive Identification Panel is an in vitro diagnostic device consisting of a panel of biochemical substrates used to identify gram-positive bacteria from clinical cultures based on their metabolic reaction profiles. It is classified as a Class 1 (lowest risk) device, subject only to general controls, representing the least burdensome regulatory category. The product code is LQL, regulated under 21 CFR 866.2660, within the Microbiology medical specialty. No special flags apply to this device.

A predicate device is a legally marketed device that a new 510(k) applicant uses to demonstrate substantial equivalence. The FDA's 510(k) pathway requires manufacturers to show that their device has the same intended use and similar technological characteristics as one or more predicate devices already cleared for commercial distribution.
Finding the right predicate is a critical step in 510(k) strategy. Manufacturers typically search for cleared devices with the same FDA product code, which groups devices by their intended use and regulatory classification. This tool helps you identify potential predicates by browsing all clearances within a product code.
Note that predicate devices must be legally marketed — they cannot be devices that were cleared but never commercialized, or devices subject to a mandatory recall. The determination of substantial equivalence considers intended use, technological characteristics, and performance data.
